.T0 all whom it may concern:

Beit known that I, ALBION M. GRANGER, of Medford, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Vater-Elevating Apparatus, of which the following is a specication.

This invention has for its object to enable a stream of water under pressure afforded by a public water-supply system to raise water from trenches or other excavations in streets or otherlocalities where the public water-serv ice is available, the desired result being accomplished by discharging a stream of water under pressure from a hydrant into a conduit communicating with the body of water to be raised, the stream being so directed in the conduit as to induce aflow of water upwardly from the body to be raised, the water thus raised mingling with the impelling-stream and passing away therewith.

The invention consists in the combination, with a water-supply system, of a portable conduit constructed to conduct water upwardly from a trench or excavation, and provided with an internal nozzle having a connection with the water-supply system, and extending along the conduit in the direction in which the water raised from the trench or excavationis to tlow.

The invention also consists in t-he application of a valve or gate placed in said conduit beyond the discharging end of said nozzle, whereby the water may be directed backwardly to flush the conduit and remove obstructions therefrom.

The invention also consists in a chamber or tube having a nozzle entering it, and extendi'ng along its interior in the direction of its length, iiexible pipes coupled to the opposite ends of said chamber and adapted, respectively, to enter the depressed body of water to be raised and to conduct such water away, and another flexible pipe connected to said nozzle and adapted to be coupled to a hydrant, all of which I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view of my improved apparatus, whereby the method above outlined may be carried into effect. Fig. 2 represents a longitudinal section of the apparatus.

f service system.

rlhe same letters of reference indicate the same parts in both the gures.

In carrying out my invention l provide a portable conduit, which is composed of a metal tube, a, flexible tube or pipe b, connected by a' suitable coupling, a', with the tube a, and extending downwardly into the body of water c, to be raised from atrench or excavation, e, and a flexible discharge-pipe, g, coupled to the other end of the tube a, throughwhich theimpelling-water and the water raised thereby may be conducted to the point where it is to be discharged; or, if preferred, the pipe g may discharge the water into an independent trough or conductor placed in the trench or upon the pavement.

i represents a metallic nozzle, which passes through one side of the tube c, and is bent inside the chamber and extends a short distance along the same toward the outer end thereof. The external end of the nozzle is coupled to a flexible pipe or hose, j, which is connected with a hydrant, 7c, or other brauch of a pipe or main comprising a part of a public waterlt will be seen that water under the usual pressure afforded by a public water-supply system, passing through the bent nozzle i and discharge-tube g, away from the body of water c to be raised, will by frictional contact create a partial vacuum in the tube a and pipe b, and thus induce a iiow of water from the body c through the pipe b into the chamber a, the water thus raised mingling with the stream entering through the nozzle t', and being carried onward thereby to the point of discharge. ln this way water has been raised by the described apparatus to a height of twelve feet from the bottom of an excavation and discharged on the pavement at a distance from the excavation. The nozzlei entering the side of the conduit and bent into line therewith enables a stream of water flowing through the conduit to follow a course devoid of abrupt curves,and therefore experiencethe minimum of resistance from friction on the sides of the conduit.

The described method is principally useful in raising water from trenches which are being dug in streets for sewer-pipes, accumulating from various causes in such trenches, so as to greatly impede the progress of the work unless it is removed.

Heretofore hand-pumps have been used for this purpose, one or more men being required to operate eaeh pump.

The above-described apparatus is now in daily use, and raises, at a oost of about two dollars per day for the impelIing-stream, a quantity of Water which would require the constant labor of from ve to six men with two hand-pumps, a large saving being therefore effected. The tube a is provided with a gate or valve, Z, whereby the pipe may be shut off to cause the Water to iiow baekwardly through thepipe b to force out any obstructionsv that may have found lodgment therein. The pipes a and g, coupled to the opposite ends of the conduit formed by the chamber a and pipef, and t-hepipe j, connecting the nozzlez' with the hydrant, are all eXible and permit the appa ratus to be adjusted to various requirements and. locations. The iiexibility of said pipes also permits the apparatus to be used as a siphon, water being supplied from the hydrant through the nozzle t' to induce or start the iiow through the siphon, the supply from the hydrant then being shut off, if desired, or continued to increase the discharge.

I claim* l Y V1. The combination, with a hydrant, of a fiexible hose leading therefrom, a nozzle forn1- ing the termination of said hose, a tube intoy which said nozzle extends, and iiexible pipes b g, leading into and away from said tube.

2. The combination, with the tube a, of the flexible pipe j, terminating in a nozzle in said tube, the iexible pipe b, leading to said tube,
